How to Install Raised Access Flooring: Step-by-Step Guide + Quick Tips

Step 1: Prepare the Subfloor

Clean the subfloor thoroughly. Ensure it is dry and level with no high spots. Use a laser level or transit to identify floor height and slope.

Step 2: Mark the Grid Layout

Use chalk lines or lasers to mark out a central starting point. Work outward, ensuring accurate spacing to match panel size (typically 600x600mm).

Step 3: Install the Pedestals

Place pedestals at each grid intersection. Fix them with adhesive or screws depending on your system. Adjust to height using a laser or spirit level.

Step 4: Fit Stringers (If Required)

For screw-down systems, connect stringers between pedestals. Use M6 screws to secure panels to stringers for added stability.

Step 5: Lay the Panels

Place floor panels carefully onto pedestals. Start in the centre and work outward to maintain symmetry and accuracy. For screw-down, fix panels firmly.

Step 6: Level and Adjust

Check levels across each section. Adjust pedestal heights where needed to ensure a flat and flush floor.

Step 7: Trim, Cut & Finish

Measure and cut perimeter panels to size. Install edge trims or ramps where needed for safe transitions.

Tyler’s Top Tips

• Always clean the subfloor thoroughly before starting – dust and debris can affect panel level.
• Mark your grid accurately from the centre to avoid uneven edge panels.
• For screw-down systems, pre-fit a few rows to double-check alignment before committing fully.
• Keep a small toolkit handy – laser level, mallet, screwdriver, and tape measure are essentials.
• Step back every few rows and check alignment by eye as well as by level – it really helps!
